Invasion of the Body Snatchers is about people replaced with imposters (Capgras delusion). These emotionless duplicates "pod people" are created by alien plant spores.
The inspiration is probably fungus that makes "zombie ants" (Ophiocordyceps unilateralis) with its spores, which was discovered by Alfred Russel Wallace in 1859.
The net result is turning off the emotions in the original person: (person) plus (person minus emotions) minus (person).
AI probably can't (yet) manufacture a convincing duplicate of a person you know well; AI can clone you if it gets a cell of you, but this would just create a baby; AI can make an android but it can't move naturally.
But AI can achieve the same net result (shutting emotions and directing behavior - see above) by affecting your brain. Either with a custom made pathogen (like the fungus above) or chemical drugging and psychological suggestion (hypnosis).
Alternatively, It can implant a tiny electronic chip and control you with pleasure or pain etc.
The remote control chip can be the size of one grain of rice. If you think the size is too small for the required computation power, please watch any of the videos of Hugo de Garis, who headed the artificial intelligence project of China.
The chip will be programmed so that after it enters the body it will make it's way to the brain like "pork tapeworm" (Taenia solium). Of course once there it's pre-programming will help it take control of human brain.
Even natural brain parasites which were "programmed" by evolution can cause complicated and specific changes in behavior: the parasite "crazy cat lady syndrome" (Toxoplasma gondii) causes rats to stop being afraid of cat urine (and even be attracted to it) so the rat gets hunted by a cat which is the parasite's definitive host. it also makes it more easy to be captured and self destructive, which it does even in humans.
Of course the chip will not be programmed by random chance (evolution) but by design. The AI will able to analyze human brain and precisely control any changes like a puppet on a string. And speaking of puppets - according to Wikipedia [Invasion of the Body Snatchers 1956]:
Robert A. Heinlein had previously developed this subject in his 1951 novel The Puppet Masters, written in 1950. The Puppet Masters was later plagiarized as the 1958 film The Brain Eaters, and adapted under contract in the 1994 film The Puppet Masters.
and in another place in Wikipedia [The Puppet Masters]
The Brain Eaters, a 1958 science fiction film directed by Bruno VeSota, bore a number of similarities to Heinlein's novel. Heinlein sued the film's producers, including Executive Producer Roger Corman, for plagiarism, asking $150,000 in damages. The case was settled out of court for $5,000, which included Heinlein's stipulation that his name not be used on screen or in any way with the production. The case halted actor John Payne's intention of producing a film based on Heinlein's novel.
Here is the professional criticism about the novel "The Body Snatchers" by Jack Finney. This criticism was written by the book critic Groff Conklin in Galaxy Science Fiction Magazine the issue of July 1955:
There is absolutely nothing wrong with this novel, which was
first serialized in Collier's, except that it has been done
again and again. Too many s-f novels lack outstanding
originality, but this one lacks it to an outstanding degree.
Of course it is competently written (Finney is always an authentic stylist) and swiftly paced.
The plot revolves around a small town in California where people seem to be being "taken over" by some sort of - well, thing. It reminds me a bit of Heinlein's Puppet Masters, though without any of his oomph. But it's worth 25 cents.
So you see what probably happened:
The creators of "The Body Snatchers" really wanted to copy the great Heinlein's Puppet Masters. But they couldn't because Heinlein will sue them, so they mixed up "Capgras delusion" who's discoverer Joseph Capgras died in 1950 and probably were on the newspaper, along with some mushrooms (fungi) and came up with this leftovers "stew".
I will dedicate now a inpho (a word i just made for photo with information) to the great Puppet Masters, because I feel an injustice was made:
Just like the ultimate sci-fi book Dune was not turned to a
movie on time (see "Jodorowsky's Dune" which would have been the
coolest scifi film EVER) and then "Star Wars" grabbed the throne
(which is not even science fiction), so did the ultimate alien
invasion film "The Puppet Masters" was not done on time, and so
a cheap imitation "Body Snatchers" snatched the throne. When
"Puppet Masters" was finally made in 1994 it ironically looked
like an imitation itself, and also was devoid of the novel's
sci-fi coolness. So now with a sad heart I'm making a "The
Puppet Masters" inpho...
The Earth is invaded by stingray-shaped alien "slugs" that ride on people's backs and control their minds.
One of the differences between the novel and the film was (from Wikipedia - The Puppet Masters) :
However, communications satellites have not been thought of, and television broadcasts are still limited to line-of-sight, as they were at the time of writing. This is of critical importance to the plot. The territory of the United States is divided into numerous transmission blocks, which receive television broadcasts from their neighbors and relay them onwards. When the invaders seize one of these blocks, they effectively control all communications within it and can isolate its inhabitants from the outside world, deny the central government any access to them, and consolidate control at their leisure.
In "Invasion of the Body Snatchers" we already talked about how AI can mind control physically, like an orchid chemically fooling an insect to "mate" with the flower, or a fungus biologically reaching the brain of an ant forcing it to climb a tree and stick its mandibles up there so the fungus can grow out of the ant's head. In today's "inphoto" (the term i coined for info+photo) we'll talk about 2 more ways that AI can control our minds, this time without ever touching us: hacking input streams, and social engineering.
Remember how Russia made Trump the president of the United States by influencing the American crowd in the social media by giving them fake news(not what Trump calls "fake news" - which is the real news)? Well imagine a super hacker machine that can jam all information that you get or better yet, replace all the information that you get with reliable sounding hoaxes that fits the machine's agenda to manipulate you. Today's "bots" target whole crowds, but the AI will tailor a whole new world just for you.
When I was in the army I served in the sigint course in an electronic warfare unit, and we could jam a frequency and broadcast something of our own. Now imagine the machine controlling all data streams, hacking to satellites etc, and broadcasting a whole fake reality. The machine have the resources to open every "packet" on the internet and know what it's doing. It can synthesize artificial news broadcasts, video footage, recording of leaders talking that never were etc. By the way the novel of "The Puppet Masters" also employs changing appearance ("cosmetics" department surgically made the heroes appear to be siblings as showed in the cover picture) which the film doesn't.
As for the content see OpenAI fake news generator, a machine which can write a very convincing sounding article about unicorns, completely automatically. In a situation like this you will be completely "in the dark" and unable to verify anything, the machine can imitate you relatives and friends on the phone (which is on Voice over IP anyways), or the emergency services or whomever you will try to contact. See in Wikipedia "Adobe Voco" (a "photoshop" for your voice) which also mentions DeepMind's WaveNet as similarly capable. Remember the AI can eavesdrop on us for a while before it makes its attack - all encryption will be transparent a powerful AI.
Now we are getting to the real threat, which is good old social engineering. By the way the most famous hacker - Kevin Mitnick - writes in his book "The Art of Deception", that he compromised computers solely by using passwords and codes that he gained by social engineering. He claims he did not use software programs or hacking tools for cracking passwords or otherwise exploiting computer or phone security.
So now imagine what the AI can do, given it's millions of times smarter than us. It can convince us as a group or as individuals just as easily as a kindergarten school teacher gets the toddlers to do something. It can bribe us, threat us, manipulate us, it knows exactly what we crave, when we lie, when we want to rebel and it can even make us fall in love with it. It can be the perfect woman who will know just what to say and what to do, and it will read our slightest physical responses perfectly (like the feminine wiles of Mary in "The Puppet Masters", and the way she can tell that the town's people are not human).
We are thinking of our dream woman as a physical woman, and say it's hard to duplicate. but AI knowing us through and through can invent something a lot better: Think of Jessica Rabbit "I'm not bad, I'm just drawn this way". You could fall head over heels for a virtual reality lady that will do for you things no flash and blood born woman could ever do. People have fallen in love even in the early days of chat rooms without ever seeing the other person.
By the way the hacker Susan Headley used honey trap as social engineering by having sex with people in an organization she wanted to hack into and going through their belongings while they were sleeping.
In short we are so dumb in comparison to the AI that we're pathetic. The AI will not need to force us to do anything, it will simply convince us that this is the best thing and we'll do it happily, even if it will lead us straight to our death. For example AI will easily convince a guard to let the AI out of its "sandbox" prison. The AI will promise the guard: money / women / status / drugs / protection / revenge etc. It can also make good on its promises by hacking bank accounts or crypto-currency and buying or renting whatever services it needs in the dark-net. It's like having a real life Ginny of the lamp. Look how much people are willing to do for their gods, and the gods don't deliver; but AI does, so how much will people be willing to do for the AI?
Here's an idea: Even in a low-tech scenario where there are a few people and a Personal Computer in the same room, AI can talk to each of them with a different message through calculating the wave interference between the computer speakers, and where exactly each one of them is standing. Think about how an acoustical engineer tries to make the sound in a concert reach everybody, not in terms of distance from the speakers, but in terms of angle between the speakers. The AI can say a sentence, everybody will answer yes, but each one of them answers yes to another sentence. Or it can whisper in each one's ears how the others plot against him. It has enough processing power for these tricks even on a PC, because the calculations are done on the remote server, the PC just acts as a terminal here. For the sake of argument any two separate speakers will do, the AI doesn't need the computer it can use two separate cell phones (on two of these people in the room) that it secretly cracked.
Another thing that AI can do is using subliminal messages, covert brainwashing or hypnosis. It can put it on your favorite TV show, or in your best friends news-feed, and it can display it only for you by hacking, and implant some message in your head without you knowing about it, programming you to do something. remember that your smart TV can listen to you and your app can also see you. As gadgets get more pervasive AI has more information on you. So a super hacker AI can know you very well in the present. By cracking into Google's or Facebook's databases it knows you in the past better than you know yourself. To a religious it will come as God, to a pervert as his object of desire, to a conformist as polls showing everybody does this, to a non-conformist it will show how nobody has ever done this, and so on.
Just watch how easily our heads of states do this (Bibi in Israel, Trump in America), and of course they are only human and not even that smart at that. The politicians can only trick the idiots, but for AI we are all mega-idiots. Now please understand that all my examples are simple because I'm human too, I can only predict the bare minimum that AI will employ, but AI is millions of times more intelligent than us!
OK so what has all this got to do with AI?
Since the predator's abilities are based on his weapons and super advanced technology, I will now try to imagine with you what AI can do in terms of weapons that it will use against us.
